Research On Tactical Network Planning And Anti-destruction Reconstruction Method Under Multi-constraint

With the environment of the modern warfare is getting worse and worse,accurate attack on enemy network nodes is becoming one of the main means to win war,meanwhile,the network shock caused by the destruction of network nodes will make lasting affect on the deterioration of tactical communications networks.Therefore,The research of network reconfiguration method is becoming more and more significant.In the paper,tactical communication network is simulated by constructing tactical virtual backbone network on the basis of a network topology model which is established through a specific algorithm and making microwave station link attenuation prediction and electromagnetic wave diffraction loss prediction,then the stability of the generated network topology is analyzed to obtain network structure satisfying the stability condition by Lyapunov analysis methods.First of all,ITU-RP.526 model is used to predict field strength of the maximum communication range of the transmitting station.Meanwhile,microwave link attenuation prediction model is applied to predict the attenuation value of sampling points on the transmission path.Secondly,topology construction algorithm based on disjoint paths and the virtual backbone construction algorithm are designed and improved to apply for the tactical communication network.The simulation proves the superiority of the disjoint path number topology construction algorithm and the virtual backbone network construction algorithm based on tactical communication network.Thirdly,The Lyapunov algorithm and Lyapunov analysis method based on the network model of tactical communication network are designed.Meanwhile,The effectiveness of Lyapunov method in network stability is verified by simulation.Finally,this paper proposes a network stability evaluation method based on Lee Lyapunov analysis.Firstly,the network topology model is generated by using the topological control algorithm of disjoint paths,then the backbone network satisfying the condition is generated by the construction algorithm of virtual backbone.Finally,The network stability of the generated network model is analyzed by Lyapunov analysis to judge whether the network meets the requirements of network reconfiguration.
